IMPROVEMENT IN ICE-CREAM FREEZERS.

Specification forming part of Letters Patent No. 131,611, datedSeptember 24, 1872.

To all whom it may concern:

Be it known that I, EDWIN HALLOWAY, of Belvidere, in the county of Booneand State of Illinois, have invented a new andImproved Ice-CreamFreezer, of which the following is a specification 2 My inventionrelates to the classof freezers wherein the revolving cream-holder hasarotary stirrer or dasher within it, and is arranged in an ice-holderplaced in a Wooden tub; and the invention consists in the combination ofcertain parts of the apparatus, as hereinafter specified.

Figure 1 is a sectional elevation of my improved ice-cream freezer takenon the line a: w of Fig. 2. Fig. 2 is a horizontal section taken on theline 3 y of Fig. 1. Figs. 3 aud4 are detail sections, showing thecatches for engaging the different parts with the dasher.

Similar letters of reference indicate corresponding parts.

A represents the outer wooden tub with a cover B, through the center ofwhich the shaft 0 of the dasher E rises. F is the ice-holder, consistingof a sheet or cast metal case with a cover, G. H is thecream-holder,which is another sheet-nletal case smaller than F, and arranged in astep, I, in the bottom thereof, so as to turn freely. This case has avery closefitting cover, K, whose flange fits down upon a rib or-flange,L, so as to insure the preventing of the ice and salt or otherfreezing-mire ture, which is to be contained in the case F, from workinginto the cream-holder. The top of this cream-holder is centered in theiceholder by the ring M surrounding it, and supported by the arms N,which spring into the annular groove 0, in the inner wall of theiceholder near the top. P is a spring-catch, arranged on the under sideof the cover K of the cream-h0lder, in. such manner that when the dasheris turned to the left it willso connect the dasher and cream-holder thatthe latter will be turned by the dasher in the ice as required tofacilitate the freezing, but when the dasher is turned the other way thespring will rise and allow it to pass by, and at the same time aprojection, Q, on the top of cover K of the cream-holder, will comeagainst a similar spring, R, on the under side of cover G, which holdsthe cream-holder while the dasher turns. This spring rises and allowsthe cream-holder to turn when the crank is turned in the direction forturning the creamholder in the ice. The ice-holder has small holes, T,in the bottom near the center, to allow a draft of cold air contained inthe tub A to circulate up through the ice, which greatly facilitates thefreezing.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- 1. The combination,with the ice-holder andcream-holder, of the ring M and arms N, substantially as specified.

2. The ice-holder, provided with the airholes T, arranged in aninclosing-tub, A, substantially as specified.

EDWIN HALLOWAY.
